Prius used infrequently, hence a couple of months between "fill-ups".
Any problem with this, & thanks ? Maybe I should try to fill only a
fraction of the tank at a time ? What's the safe max "life" of gas in
the tank ?

If you're worried, use GOOD gas (Shell) and a fuel stabilizer.

Fact:  around here, anything other than Shell gas makes lawnmowers run
like crap.  A car is more resistant to whatever's wrong with the other
fuels, but if you really want to give your Prius every chance you can...

Also, consider going up an octane level.  Octane actually goes down over

I disagree on the higher octane thing, the Prius has been known to throw a
MIL for misfire codes on higher than 87 R+M/2

The purpose of starting with higher octane is that by the time the tank
goes down to empty a couple of months later, it's down to a lower octane
